APPARATUS FOR CHARGING INCLINED RETORTS.

SPECIFICATION forming part of Letters Patent No. 717,575, dated January6, 1903. Application filed July 14, 1902. Serial No. 115,486. (Nomodel.)

T0 at whom it may concern:-

Be it known that l, WALTER RALPH HER- RING, a subject of the King ofGreat Britain and Ireland, residing at Granton House, in the city ofEdinburgh, Scotland, have invented a new and useful Improvement inApparatus for Charging Inclined Retorts, of which the following is aspecification.

My invention relates to an improved construction and arrangement ofcoal-charging chute for use in connection with inclined retortinstallations.

. The object is mainly to provide means for varying the inclination ofthe traversing shoe of the charging-chute, so as to accommodate thevarying physical characteristics of the coal used, such variation ininclination being under the control of the attendant and being capableof rapid adjustment by him either prior to or during the actualoperation of charging. I attain this object by the mechanism illustratedin the accompanying drawings, in which Figure 1 is a side elevation of acoal-charging chute in position having my improvement applied; and Fig.2 is a cross-section of Fig. 1 on the line a Z).

Similar letters refer to similar parts in each of the views.

A is the shoe, which is secured beneath the body of the traveling chuteB and projects into the mouthpiece O of the retort. The noseof the shoeA is pivoted at D and is suspended at each side by a link E, adjustableat F. The upper ends of the suspensionlinks E are attached M6? to theside plates of the hood H, upon which the trolley wheels or runners Kare fixed, these wheels or runners K working upon or within guide-railsL,

attached to the lower part of the body of the chute B. The suspensionlinks E serve, therefore, not only as a means of pivoting the shoe A,but also as a means of adjusting the level of the'nose of the shoe A toovercome the slight inequalities in level of the various retorts.

The upper end of the shoe A is inclosed Within the aforesaid hood H andmoves up and down therein in accordance with the adj ust-ment of ahand-wheel M and screw N or other simple mechanical device. Consequentlythe angle of inclination of the base of the shoe A is alterable at will,so that the coal descending from the body of the chute B strikes thebase of the shoe and is directed into the retort O at whatever angle theshoe A may have been adjusted for. In Fig. l the dotted lines at Aindicate the raised position of the shoe A and those at M and N thecorresponding positions of the hand-wheel M and screw N. I

When the apparatus is used inconnection with the upper tier of retorts,a handle P is fixed beneath the shoe A. When applied to the middle and"lower tiers of retorts, a handle B may be attached to the end plate ofthe shoe A.

What I claim as my invention, and desire to secure by Letters Patent,is-

lQIn apparatus for charging retorts, the combination, with a chutehaving guide-rails at its lower part, of a hood slidable on the saidrails longitudinally of the retorts, an inclined shoe, links pivotingthe lower part of the said shoe to the said hood, and means foradjusting the position of the upper end portion of the shoe within thesaid hood, substantially as set forth.

2. In an apparatus for charging inclined retorts, in combination, thetraveling chute B, the guide-rails L thereon, the hood H having wheelsor runners K, the shoe A pivoted at D, the suspension-link E adjustableat F, the hand-wheel M having screw N, and a handle attached to the saidshoe A, substantially as described, for the purposes specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WALTER RALPH HERRING.
